To a 1071.071? it may concern:

B(') it known that we, AMos OALLEsoN and ADRIAN DEXTER ADRIANOE, residing in the borough of Brooklyn, in the county of Kings and State of New York, and. ANTON DUPPLER, residing in Jersey City, in the county of Hudson and State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in Warp Twisting In Machines; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains. to make and use the same, reference being had to the accompan ing drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates to the art of replenishing the warp in looms by twisting onto the ends of the old warp the ends of the lien and it consists in certain improvements on machines of this nature secured. to Albert Goss by United States Letters Patent Nos. 648,738, 675,350, and 686,724 and to Krty and Duppler by United States Letters Pat- .ent No.'695,566. 1

Fig. 60 is a side view of a detail shown in Fig. 59. Fig. 61 is a view of a detail shown in Fig. 59. Fig. 62 is a view of a detail shown in Fig. 58. Figs 63', 64, and 65 are views illustrating a means attached to the frame shown in Fig. 58 for facing up the wipingsurfacesof the members of the twisting mechanism. Fig. 66 is a side view, and Fig. 67 a plan view, of a certain carriage on which the twisting-in machine proper is mounted in the frame shown in Fig. 58. Fig. 68 is a rear view of said carriage. Figs. 69 and 70 illustrate details of said carriage, and Fig. 71 is a view illustratin diagrammatically how each warp is applie in position to be operated upon in the twisting-in machine proper.

The machine isdesigned especially with the idea of applying it in the operation of twisting in new warps in the process of weaving, thus employing it to supersede'the usual hand operation. For this purpose it may be supported in operative position on the loom by any suitable brackets. fer to mount it upon an automatically-movable carria'ge, such as is shown in. Figs. 66 to 70 of the drawings, said carriage being mounted upon the guides which. are arranged in a frame, such as is shown in Figs. 57 to 60 of said drawings, and usually employed where it is expedient to remove the old warp, toether with its harness and reed, from the l oom in'order to perform the twisting-in operation. I

In the drawin s, a designates the base of the machine, an I) and 0 two uprights, the

- former of which is higher than the latter and is cast integral with the base, while the latter is preferablysecured by screws cl or otherwise to said base. In said uprights is'journaled the main shaft e, carrying a bevel-gear f, which meshes with another bevel-gear g on a drive-shaft h. Said shaft h is journaled in a casing structure 2', which is secured by screws to the back of the upright 0 and covers the bevel-gear and certain other mechanism hereinafter described. On the shaft h is re: movably secured a drive-wheel y'. The shaft Fig.

' cover their joint.

However, we prefront end the stationary member 0 it being arranged obliquely in the machine adds very materially to convenience in operating the machine, since all the power is taken in b hand through the drive-wheel 7'.

On sha t e are secured a gear k, a cam- Z having a peripheral cam-groove m, and a PHI-1' ion n, the same being arranged in the order named, with the pinion next adjacent u right b. The front of the upright b is 'forlne wlth a cavity 0, and in this cavity are secured on shafte a roller-carryingdiskpand a in-wheel g, disposed in the order named, wit the disk adjacent the end of the shaft e.

The upright b is formed with an integral forwardly-projecting sleeve s, which constitutes a bearing for a shaft t, that carries a pinion (not shown) which meshes with another 'inion (not shown) journaled at u in upright and in turn in mesh with the gear 12.. The gearing just described is found in Fig. 6 of the Krey and Duppler atent aforementioned. As in that patent, the front end of shaft t has pivotally connected to it the rear end of an extension-shaft c, which carries at its end a spiral w and which may be folded around on shaft t, so as to turn the spiral out of the way. When shaft 0 is thusdeflected, it may .be supported by a rigid arm as, secured horizontal y in a bracket 1 on u right I). The shafts tand i: may be kept a ined, as in the Krey and Duppler patent beforementioned,

by a sleeve 2, arranged to slide on them and The spiral w is enerated at the end portion of shaft 4. an projects rearwardly. It carries two other spirals 1 and 2, the former projecting rearwardly and the latter forwardly, all said spirals cooperating to properly advance the threads.

3 is a normallystationary shaft mounted in both uprights b and c and carr ing at its f the twisting mechanism. In order to delicately adjust said meinber, this shaft is ada ted for slight movement longitudinally, an to this end carries a fixed collar 4, between'which and the upright c is coiled a spiral spring 5. On its rear end, which protrudes through the upright c, is secured by a pin 6 an arm 7, whose free end is forked and fits over a fixed pin 8 on said upright in such manner as to keep the shaft from turning. Said arm is split, as at 9,

IIO

and in its split portion receives an adj ustingscrew 10, which is tapped into the upright c.

By manipulating this adjusting screw the shaft 3 canbe very delicately moved longitudinally so as to bring the stationary member of the twisting mechanism into just that relation with the movable member of said mechanism as is necessary to secure the perfect co: operation of said members. When once adjusted, the parts can be secured in fixed relation by a set-screw 11, mounted in the split portion of the arm and adapted for causing it to bind on the adjusting-screw 10.

or other simi ar material.

The twisted mechanism is shownin Figs. 26 to 34 of the drawings. The stationary member thereof consists of a bracket 12, fixed to the end of shaft 3 and having a segment-shaped portion 13 and an arc-shaped pad comprising a metal back 14 and the pad proper, 15, Which may be of rubber or other similar substancel The back 14 has headed studs or projections 16, and these fit into slits 17, formed in the edges of the segment 13. The slits 17 are so disposed that when in operation the wiping action of the twisting members forces the studs against the-close ends of said slits; but to insure against accidental separation of the parts a plate-spring 18 is mounted on the bracket 12 in such a manner as to bear against one of the studs 16 and hold it in its slit. The rotary member of the twisting mechanism consists of a segment-shaped bracket 19, carried by a s indle.2Q,. and a pad comprising a metal bac 21 and a face or ad proper, 22, formed of rubber The back 21 is secured to the segment 19 by headed studs or projections 23, engaging in slits 24, formed in the ed e of the segment 19 in such manner that W en in operation the action of the two members of the twisting mechanism forces said studs against the closed ends of the slits.

In order to cushion the pad onthe segment 19, spiral springs 25 are set in sockets 26, formed in the bottom of recess 27 in the segment 19, said springs being covered by small .socketed plates 28, 'whichdirectly bear against the back 21 of the pad. The pad is thus adapted to automatically adjust itself true to a proper coaction with the pad of the stationary member of the twisting mechanism. On the segment 13 is arranged a V- shaped thread-concentrator 29, into which the two threads to be twistedare ultimatelyforced by the spirals above described. With this as a detent coi'iperates for the purpose of cutting the threads a knife 30, which is held in an arm 31 in between a grooved projection 32 at the end of the latter and a plate-spring 33, which penetrates said arm, overlapping the knife, and is made to press against the latter by a set-screw 34, tapped into the arm on the farther side thereof. by a spindle 35, journaled in a brack t 36, se-

cured to the bracket 12,- said spindle also carin 'a toe 37 a ainst which wi es a cam 38 on the endof the spindle 20. After the cam 'has'turned the arm 31 to effect the cutting of the thread the arm is returned by a spiral spring 39, connecting the toe 37 and the bracket 12. y

In the modified form of the thread-cutting means shown in Figs. 40 to 42 the concentrator 29 has a rebend 40, receiving cutters 41 and 42, the former having a cutting edge 43 crossing that formed continuously at the periphery of the other, 42, which is a disk, the

This arm is carried.

said cutters being mounted on a spindle 44,

set in the concentrator 29 and the se ment 13. The threads in order to be cut by t e action of the twisting mechanism enter the notch formed by the intersection of the cutting edges of the cutters 41 and 42, which have a scissors-like effect, and the cutter 42 is ar ranged to rotate on the spindle 44, so that the portion of its edge which is presented to the threads is constantly changing. 44 is a spring pressing cutter 41 against cutter 42.

The spindle 20 is journaled in the uprights b and c and carries between said uprights a gear 45, meshing with a gear 46, in turn mesh- 7 ing with the gear 7:. The gear 45 and the hub 47 of a disk 48, secured on the rear end of the spindle, coact by abutting against opposite sides of the upright c to prevent the spindle from lengthwise movement.

49 is a rock-shaft journaled in the uprights and carrying a crank 50, connected with an eccentric point 51 on the gear 46 by a link 52. 1 The forward end of this shaft carries a finger '53 of the shape indicated in Figs. 1 and 2. Ina sleeve 54, fixed in the upright 15,. is arranged a longitudinally-reciprocating shaft 55. This shaft carries at its rear end an arm 56, having a roller 57 at its upper end which moves in the camway of caml and whichis penetrated by a fixed stud 58, pro- 'jecting from the upright b, which acts to keep the arm vertical, and consequently shaft 55, from turning. The forward end of shaft 55 carries a fork 59 of substantially the shape best shown in Figs. 17 and 22, the ends of 1 said fork being provided with wire thrcadholders 60, having upward bends 61 therein. These wires by their inherent elasticity accurately keep the threads within the hold of the fork until the last moment, when they as freely permit the release of the threads.

On sleeve 54 is clamped by a set-screw 62 I the split ring 63 of a bracket 64, in which is journaled a spindle 65, rotated from spindle 20 by bevel-gearing 66 and carrying a spiral 67, whereby after the threads are united they are forced out clear of the twisting mechanism. The spiral as it moves them keeps them separated, and thus prevents possible entanglements growing out of the torsional reaction of the threads following the twisting operation.

68 represents four sleeves which are fixed in the upright b. naled the hook-bars 68 (shown in Figs. 7 and 8,) having milled shoulders 69 thereon,

In these sleeves are j0u rwhereby they may be manually rotated when occasion requires. Each hookbar carries a pinion 70, arranged to freely rotate thereon and disposed in a cavity 71 formed in the back of the upright I), abutting against the vertical wall of said cavity. It also carries one member of a clutch 72, formed with a projection 73 on the side thereof adjacent the pinion, which where 87 is a star-wheel adapted to be inter- These rods are simply fixed in the sleeves 6 front face of the upright b.

latter forms the other member of the clutch,

having a notch 7 1 to receive said projection. Clutch-72 is held against the pinion by a spiral spring 75, coiled about the hook-bar and dis posed between clutch member 72 and plate 76. The several pinions 7 1 are in mesh with a gear 77, which is j ournaled on a pin 78, projecting rearwardly from the upright and supporting-the front end of a guide 79, which is held to the rear-upright by a screw 80. The plate 76 abuts against the front end of the guide 79 and is penetrated by the pin 78, a

said plate and gear 77. The rear ends of the hook-bars thus journaled in the upright b', as well as the plate 76, are peripherally channeled, as at 82, to receive notched plates 83, fixed to wings 84, projecting laterally from a carriage 85, consisting of a block snetrated Said carriage carries an antifriction-roller 86, which works inthe camway of the cam l, wherefrom said carriage is reciprocated. Periodic rotations are transmitted to the hookbars by the mechanism best shown in Fig. 4,

mittently rotated by the pin on pin-wheel q, and where 88 is a gear rotating with said star-wheel and engaging one of the pinions 70. It will be understood that the hook bars are arranged in vertical pairs in which pair are set relatively reversely, as in the patents hereinbefore re ferred to. It is found, however, in practice that one hook-bar in each pair-can be dispensed with and in its place a fixed rod 89, used to maintain the cross. (See Fig. 54.)

being made a little longer than the hookbars, so as to insure against the threads slipping It is found desirable to eni-' ploy a stationary fork 90 to keep the fibers or ilaments of the dificrent threads from entanglement with each other, which fork can be secured to the plate 91, which covers the 92 is a reciprocatory frame which is ar ranged to be moved vertically, the same as in the patents above referred tot'. e., by a roller 93 on the disk p, which engages in a curved slot 94 in said frame 92. Said frame 92 is guided in the upright b, substantially the same asdn the patents above mentioned, and it carries at its lower end, which is bifurcated, horizontal rods 95. i

96 represents the stationary horizontal rods or thread-guides with which said rods 95 coact, the same being located one on each side of the pair of rods 95 andina horizontal plane substantially between the limits of movement of said rods 95 vertically, said rods 95 and 96-coacting, as in the patents above referred to, to assist in any loosenipg of the threads-from each othein- 97 is an arm forming a guide for the threadclamps, the samebeing secured to the top of the frame 92 by a screw 98. Said arm is formed with a longitudinal horizontal opening 99 and a longitudinal vertical opening 100, which latter produces two pairs of guideways 101. The vertical wall 102 at the .free end of this arm is formed with two openings '103'and is covered by 'a rectangular plate 104. In holes 105' in this plate and in sockets 106 in the opposite end of the arm are mounted rods 107, on which are coiled springs 108, the openings 103 in the wall 102 being provided for the reception of said rods. On the guideways 101 move carriages 109, (see Fig. 49,) consisting of metallicplates having their upper and lower edges rebent to fit over the guideways 101. In the rebent portion of the top of each carriage i's journaled an antifriction-roller 110, which runs on the top guideway 101. The springs 108 bear against lugs 111, projecting from the carriages 109, and may be adjusted by a block 112, with which they contact at their rear ends and which is mounted on said rods to slide thereon, having a set-screw 113, whereby it may be fixed at any desired point. The carriages are thus pendently of each other. of each 'carria' corrugated pa s 114, of rubber or the like, against which may be made to impinge a correspondingly-corrugated pad of a clip 116, hinged to the carriage at 117.

1.18 is-a latch pivoted to the front end of each carriage and ada ted to engage with a projection 119 on the c ip 116 to hold the clip against the carriage closed. Forward movement'of 'each'oarriage is vlimited by the lug 1 11 coming up against'the plate 104.

120 represents latches for temporarily holding the carriages back against the tension of their'spring, the same being pivoted in the upper end of the frame 92 and adapted to engage the nibs 121 on the top rebent portions of the carriages.

' 122 represents simply handles whereby to manually move the carriages.

123 is a horizontal bar carried in a bracket The outer surface eis lined. with horizontally 124, fixed to the under side-of the arm 97.

The two sets of warp-threads, old and new, being clamped in the respective carriages,

while the same are held back by their latches 127.whereby when one arm is turned on its pivot the other will also turn. Thus in arranging the warps in the machine (it being understood that they at this time stand in between the arms of the bracket) the bracket is first opened out by turning arms 125 outwardly, so as to afford clearance. In the ends of the arms 125 are pivoted fingers 126, projecting toward each other and connected with levers 127, pivoted concentrically with said arms by links 126. Each lever 127 is connected with a lever 128, fulcrumed at the back of the upright c by a connectingrod 129, made in two parts coupled together by a turnbuckle 130, so as to be adjustable longitudinally. 131 is a detector-lever ful- CIUDGd in the same bracket 132 in which levers 128 are fulcrumed,each detector-lever 131 being pivotally connected with a lever' 128. In th. shaft h is journaled eccentrically thereof a longitudinally-extending rockshaft 133, the arm 134 at the end thereof, which protrudes through the bevel-gear g, being normally in line to be engaged byone of the levers 131, (when the latter are disposed as seen in Fig. 11,)so as to be rocked thereby, and thus turn the arm 135 at the other end of said rock-shaft out of the way of a ball 136, arranged in arecess 137 in the bore 138 of the hand-wheel 7'. Normally a s ring 139 keeps the arm 135 against the bal 136, and thus forms a clutch whereby the hand-wheel is interlocked with the shaft h; but when shaft 133 is turned arm 135 and ball 136 disengage,

and so permit the hand-wheel to turn freely on the shaft. Therefore if both the threads which are immediately engaging the fingers 126 as they are advanced in the operation of the machine are intact they will move said fingers outwardly, and so cause levers 131 to be moved out of the path of the arm 134, so

that the clutch will not be broken but if one thread is broken the corresponding finger will not be actuated, and so its lever 131 will be left in the ath of arm 134, so as to break the clutch an ermit the hand-wheel to rotate without driving the machine. In order to reset the mechanism whereby the levers .131 are normally caused to be thrown out of .the path'of the arm 134, the means shown in Fig. 11 is employed, where 130 is a springactuated paw having a laterally-projecting arm 131, which is movable into the ath of a lug 132, carried by each link 129. hen the carriage 85 moves back, the pawl, standing substantially vertically with its arm impinged against the lug 132, causes links 129 to be moved back also, thereby resetting the mechanism of which they'form a part, and as the carriage reaches its rearmost position said pawl brings up against a lug 133, which turns it on its axis, depressing its arm out of engagement with the lugs 132.

Referring to Figs. 57 to 70, 140 is a suitable frame in which is provided means for journaling the beam 141 for the old warp and the beam 142 for the new warp. 143 designates gearing driven by acraukj-t-t, whereby to wind up onto the old warp-beam the new Warp a er the twisting-in is effected. 14-5 is a rod on which travel rollers 146, arranged at the back of the carriage 147, which at 14L receives the baseaof the twisting-in machine proper, which may be clamped thereto by a thumb-screw 149 in a dovetailed groove 150. The carriage is supported partly on the rod and partly by a leg 151, which pro ects downwardly, carrying an antifriction-roller 152, bearing against the side of one ofthe tie rods 153 of the frame 140. 154 is a shoulder on leg 151, between which and a cam 155, having a handle 156, a spiral spring 157 is disposed. This spring normally presses the cam up against a lever 158, which is fulcrumed in the carria 'e and carries at its free end a roller 159, ta ing against the under side of the rod 145. By turning the earn the roller 159 is pressed up against the rod 145, so that the latter is tightly clamped between said roller and one of the rollers 146. Said roller 146 is mounted on a shaft 160, journaled in the carriage and carrying aworm- Wheel 161 which mesheswithta worm 162 on a stub-shaft 163, fixed in the carriage. Fixed to rotate with the worm is a ratchet 164, adapted to be engaged by a pawl 165, pivoted in the arm 166, fulcrumed on stub-shaft 163. Said arm is connected with an eccentric-point167 on the disk 48 by an adjustable itman 168. 169 is a disk having its edge cut over the periphery'of the ratchet, except for a portion thereof, the same being mountedon shaft 163 between the ratchet and arm 166. Said .disk carries a pointer 170, whose extremity may be engaged in any of the notches 171.0f a dial 172 by turning the disk so the turned-over edge portion of the disk will be made to cut off more or less of the teeth of the ratchet from engagement with the pawl. Thus, the twisting-in ma chine proper being in operation, it will be caused to bodily advance across the warps as the Work of twisting-in proceeds, according as the disk 169 ismade to expose more or less of the teeth of the ratchet to the action of the pawl.

In a framework 173 are arranged for adjustment horizontally-vertical rods 174, carrying adjustable horizontal rods 175 and 176. From the rods 175 by cords or the like 177 the reed 178 of the loom is suspended, said reed being prevented from lateralmovement by a knife 179, securedadjnstably on a horizontal may be carried by a bracket 186, being laid in between lugs. 187 of clips 188 on said bracket. The means for supporting the new warp-roll 142 may be brac ets 189, having teeth adapted to be engaged by pawls 190 for holding the brackets at any desired height.

'191is alever for adjusting eachbr'acket to the desired height. One of these brackets may be guided directly in the frame 140.- The other is arranged in a casting 192 mounted for movement laterally on tubular braces 193 of the frame'140. Said casting may have a roller 194 bearing against the upper tube 193, against which it is held by the tensioni-means 195 for thewarp-roll 142. On the framework 173 is mounted a bracket 196, having a plate 197, between which and a disk 198, having an abrading-face 199, the rubber faces of the two pads of the twisting mechanismmay be disposed. The plate 197 is formed with orifices 200 and 201 to receivethe studs on the metal backs of said pads, the studs for the pad of the movable member of the twisting mechanism being received by the orifices 200 and those for the pad of the stationary member being received by the orifices 201. By making the studs of the pad for the stationary member bind in the orifices- 201 said pad will be held sui'liciently fast-in plate 197 during the operation of facing its rubber surface by means of the abrading-disk 198; but since the studs on the other pad are slightly longer and'since the plate 197 is of uniform thickness a plate-spring 202, guided on a shank, 203, projecting from the plate 197, may be arranged to abut against the heads of said studs, being there held by'a spring-actuated lever 204.
